Hetero-plane beam synthesis using 60 GHz band 3-D phased array antenna module

A 60GHz band 3-dimensional (3-D) phased array antenna module has been fabricated and hetero-plane beam synthesis is demonstrated. Two separated 2×2 end-fire dipole array antennas in different (z-y and z-x) planes are configured in a multi-stacked substrate module. For x-direction, z-y plane array antenna is used and for y-direction, z-x plane array antenna is used. In order to achieve higher antenna gain at intermediate region between x and y directions, hetero-plane beam synthesis is employed using two array antennas in different (z-y and z-x) planes. Measured radiation patterns are in agreement with simulated radiation patterns and wider 10 dBi beam coverage area of 150° in azimuth and 60° in elevation is obtained. The results show the effectiveness of proposed hetero-plane beam synthesis.
